THE MECHANICAL cons'r-nuc'rron comrm, on CINCINNATI, care, A conrons- TION OF OHIO.

To all whom it may concern Be it known that I, VILLIAM a citizen otthe Unitedbtates, residix gf dt: Cincinnati, in the county of'I-Iamilton fnd State of Ohio, have; invented certain" ew rand useful Improvements 'in Mechztnieiztl Stoliers, of which the following @fSPCL invention relates A v chanical stokers in which the. fuel isja-utomatically fed through the usii lfuel-doon pen1ng,'and is designed more partmularly for use in locomotive stokers In this class.

of stokers it is sometimes necessary to clear the fuel-door opening of .thegobstructions,

The object of myinventionlis tof prow idea method of mounting the striker fee d conduit winch permits easy and instantaneous clearance of the fuel-door opening and permits easy and instantaneous replacement of the stoker parts in their working position,

and my invention consists in the parts and here-i combination and arrangement of parts matter described and claimed. In the drawings, Figure 1, 1s a'rearele- -\'ati on showing my improvement in connection with a locomotive stoker with the parts in pOSltlOI1 for automatic stokmg; Frg. 2, a
